Sine Cosine Potentiometers - nonlinear
Special potentiometer with sine/cosine signal
Sine/cosine potentiometers represent a special case in the range. They allow conductive plastic potentiometers to be operated as "multiturn potentiometers", so to speak, for the entire 360° range. This is achieved by using two wipers on the resistance track. One wiper is used for sine and one for cosine at 90° intervals.
To pick up the signal, two terminals each for positive and negative voltage (opposite), as well as two for ground (also opposite) are placed on the resistor track. When the shaft rotates, a continuous, periodic signal in sine and cosine form is generated at the sliders.
The sliders always provide a signal for the 360° range and there is no dead zone as with standard conductive plastic potentiometers. Due to the possibility of combining the two signals in the evaluation, a digital incremental signal with information on the direction of rotation can be generated by interpolation.
